語彙

1. Origins, structure, and basic meaning

• Structure: 語彙 is read as ごい and is a collective noun for the body of words known, used, or contained in a language, person’s repertoire, or text.
• Basic usage: Use 使える語彙が増える for expanding usable vocabulary and 文章に合う語彙を考える for selecting wording suited to a passage.

2. Common pitfalls and similar expressions

• Individual word and collection
  • 語彙 normally refers to a body of words; an individual item is more clearly called a 語 or 単語.
• Receptive and usable vocabulary
  • Words recognized while reading and words one can actively use are overlapping but not necessarily identical sets.
